Abstract (en)
[origin: EP0313365A2] A control rod support 100; 110; 100 min has plural, parallel axial extending passageway openings therein for receiving corresponding control rods 30a of a control rod cluster 30; 34. Spaced interior side walls 103a, b; 113a, b; 103a min , b min of the support 100; 110; 100 min defining the channel 103; 113; 103 min form junctures 95a; 95b with the interior side wall 103a, b; 113 a, b; 103a min , b min defining the passageway opening; and planar wear surfaces 105a, b; 115a, b; 105a min , b min extend from the respective junctures 95a; 95b of the channel-defining interior side walls 103a, b; 113a, b; 103a min , b min a sufficient lateral distance to provide planar-to-convex wear surface interfaces 105a, b; 115a, b; 105a min , b min with the corresponding, contiguous surface segments of a generally cylindrical control rod 30a which is received through the passageway opening and urged against the junctures.
